PLANING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 404348, dated June :11, 1889.

Application filed December 13, 1888. Serial No. 2953457. (No model.)

To call whom it may concerns Be it known that I, ERNST F. AUTENRIETH, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Planing-Machines, of which the following is a specification.

My improvement relates particularly to the presser-bar employed in planing-machines for pressing the lumber downwardly as it passes over a surfacer.

I have only illustrated such portions of a planing-machine as are essential to an understanding of my invention.

In the accompanying drawings, Figure 1 is a plan or top view of a surfacer for a planin gmachine, together with a presser-bar embodying my improvement. Fig. 2 is an end view of the same. Fig. 3 is a side elevation of the presser-bar and its attachments.

Similar letters of reference designate corresponding parts in all the figures.

A designates a surfacer by which the under side of a board is planed. The surfacer is mounted upon a shaft A', deriving motion from a pulley A driven in the usual or any suitable manner.

B designates the presser-bar. This presserbar extends horizontally of the machine. It is supported near one of' its ends upon an upright arm B', which arm is pivoted near its lower end upon a portion of the main frame of the machine, so that it may Swing freely.

B designates a longitudinal slot formed in the arm B'. Through this slot, and also through the adjacent end of the bar B, ex tends a clamping-bolt a. By loosening this clamping-bolt the adjacent end of the bar B may be adjusted into different vertical positions, 'and by tightenin g the nut a' upon said bolt the bar may be clamped in any position into which it may have been adjusted. The other end portion of the bar is received within a pocket & formed between a collar C and an upwardly-extending projection b on said collar. The collar O is provided vertically with a suitable aperture, through which extends a screw-threaded support D. Nuts D', engaging the screw-threaded portion of the support D-one above and the other below the collar C-prevent vertical movement of the collar.

Between the upper of the nnts D' and the collar C is a ring or Washer D surrounding the support D. This ring or Washer is provided with a projecting portion d.

When the upper of the nuts D' is loosened, the ring or Washer D may be rotated to bring the projecting portion d' over or away from over the bar B.- NVhen over the bar B and the nut D' is again tightened, the bar cannot be lifted out of the pocket a WVlen moved away from over the bar B, the latter may be freely lifted out of the pocket. The lower portion of the support D (indicated by the letter E) is unscrew-threaded and is adapted to be passed freely through a suitably-formed aperture e, eXtending vertically through a portion of the frame of the machine. I have shown a set-screw f for retaining the support D in any position into which it may be adjusted within the aperture e. It will be seen that this arrangement not only admits of a Vertical adjustment of the support D within the aperture e, but it also furnishes a detachable connection between the support D and the frame of the machine. This is advantageous, because it is often desirable to remove the surfacecutter A and replace it with a molding or other cutter. All that is necessary to do in such case is to loosen the setscrew f and lift the support D bodily from the aperture e, when it, together with the bar B, may then be swun g freely over upon the pivot of the arm B'. This is advantageous, because in order to thus swing the presser-bar away from over the surfacer it is not necessary to adjust the nuts D'. The adj ustment of the support D, made possible by this connection with the frame, admits also of slight variations in adjustment, where great accuracy is not required, without manipulating the nuts D'. Upon the bar B is a vertical ly and horizontally adjustable presser F, of` ordinary Construction.

By the above arrangement the bar B may be swun g at any angle by leaving the bolt a fixed and Operating the nuts D', or, in case quick adjustment is required, by loosening i the set-screw fi What I claim as my invention, and desire to secure by Letters Patent, is-

IOO

1. In a planing-machine, the conbination, with {t presser bar, of Et swinging support therefor, to which the bar is connected near one of its ends and upon which it is adjust&- ble, a support for the bar near its other end having a screW-threaded portion and an unscreW-threaded portion formed With the screwthreaded portion, the screW-threaded portion being provided with nuts, Whereby the bar may be vertically adj usted, and the unscrewt hreaded portion having a detachable connection With the frtme of the machine, substantially as specified.

2. In a planing-nachine, the eombinaton, With a presser -bar, of ft swinging support therefor near one end, a support for the same n ear the other end thereof, com prisin g a screwthreaded portion and an unscrew-threaded portion, said screw-threaded portion being provided With nuts, Whereby the bar may be adj Listed vertically, and the unscrew-threaded portion extendingloosely through an aperture in the frame of the machine, and a set-screw for securing said unscrew-threaded portion in said aperture, suhstantially as specified.
